-TO WHOM IT MAY OONCERN:

Beit known that I, C. C. BLODGETT, of Wutertown, in the county of Jefferson, and Stute of NewYork,

. have invented cert-ain new and useful Improvements in Devices for Elevating and Operating Clutches or Grapples for Sustaining Hay-Forks', and -I hereby declarethejfollowing tobe a full, clear, and exact description of the same, reference being had to the accompanying drawings.

It is well known that the tackle by means of which a horse 'hay-fork is usually suspended andolevated and lowered, is attached-to a clutch which `catches upon the Abeam or rafter from which itis desired to suspend the fork. Thisl beam is oftentimesatquite a distance from the ground, and, in'm-ny-instances, cannot be reached by ordinary means, so that i't'becomes a matter-ol` some difficulty either to cause the clutch to catchnpon'l'the beam, or to disen-gage it therefrom. l

vThe object have in view is to overcome this'diflculty, and to this end'I employ ade'vice which consists of two arms, attached to a handle outl suitablelength, and nrrangedtoy engage with thejaws of the 'clutch in thev manner hereinafter described,so that, by menus of said device, the clutch may be elevated towards the beam which it is to gra-sp, and its j aws be either 'forced and held open, or permitted tolclose, according as it is desired to engage the clutch with or disengage it from the boum. v

To enable those skilled in the art to -understand und use myinvention, I will now proceed to describe the manner in which thefsame is or may be carried into effect, by reference to the accompanying drawings, which represent a perspective view of clutch and device for elevating and operating the same.

The clutch-operating device consists of two arms or horns Gr H, which project from a' rod, F, forming` part of the handle A. The upper arm G is fattn'ched iminovably to the rod F; the lower one, H, -on the contrary, is nttachedto aisleeve, m, which slides u pon the rod. Encirclingtha't part of the rod between the two arms`,is a. spring, n, which presses down upon the sleeve m, whose downward movement is limited by a pin or stoppp', on the rod. The upper and ,lower arms G H project from the same side ofthe rod, and to the lower arm is secured u cord, t, which passes up loosely-through' the'shoulder of the a'r'ni lGuiand over a pulley, e, mounted on thetop of the rod F. The ro'pe'thence extends downwards, so ns to be within convenient reach of the operator. By,

`pulling on the rope, the sleeve 1n, with its arm H, will be raised toward the upper armG, and-it' the strain on the-rope be relaxed, the spring'n will force the sleeve down until it is stopped by the pimp.

This deviceis applied to the upper end of one clutclifjew E, and the lower end of the other, D, asocket, .'z: y, being formed in euch for the reception of' thernrms. The operation is us follows:

' When the tackleis lattached t'o the chuin'cl, :rnd it is desired to. engage the'clutch with the beam or ruiter from which the hay-fork is to be suspended, one of the arms, Gr, is inserted in the socket a: in the upperl endof the jnwE, and the other-arm H is inserted in the socket y in thelower end of the janvi). The clutch and clutch-operating device 4nre'now raised bymeans of the handle A, untilthe clutch is near the beam when the operator pulls on the cord t, as represented inlfig. 2, seas to raise the sleeve m -und arm H, and consequently the lower end of thejaw E, thus-causing the clutch to open. As soon ns one of the jaws ot` the open clutch has caught upon the beam, the l operator loosens his hold on the cord t, whereupon the spring-'n forces down-the sleeve mand arm H, closing' the jaws, and causing the clutch to vgrasp the beam tightly. The -a'rms G H, by meansof the handle, are now drawn out from their, sockets :v y, and the clutch is ready for use. I

Whenever it is desired to disengage theolutchI from the'beain, the 'clutch-operating device is raised until the arms G H can be inserted in their sockets my. The operator then pulls down on thecord t, which, as above explained, causes the separation of the jaws D E, und admits ofthe clutch being readily disengaged andremoved from the beam; I

Hoving nowdescribcd my invention,'aiid the vmanner in which' the sume is o r may be carried into efi'ect, what I claim, and desire to secure by Letters Patent, isl n The clutcl1-clevatir\g and operating device herein described of the accompanying drawings, arrangedv to 'operato in combination with n. clutch or grapple, substantially in the manner and for the purposes shown and set forth. i Y v In testimony whereof', I have signed my name to this specifica-tion before the subscribing witnesses.
